ErrCellStyles

ErrCellStyles

Error message

the cell styles exceeds the %d limit

What it means

Formatted error ErrCellStyles returned by NewStyle when the style table (CellXfs) already contains MaxCellStyles (65430) entries, the OOXML limit; the guard rejects creating one more style because Excel cannot address it.

Solutions

1. Reuse existing styles instead of creating new ones
2. Close and reopen the workbook to start with a fresh style table
3. Audit for styles created in loops or per-row calls
